BOBBIN.

SPECIFICATION forming part of Letters Patent No. 557,873, dated April 7, 1896.

A li ati fil d June 11, 1895. Serial No. 552,402. (No model.)

To all whom it may concern/.-

Be it known that I, GURDON PENDLETON, J12, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a new and useful Improvement in Bobbins; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to the manufacture of bobbins for winding, spinning, and other purposes, wholly or partly of thin or sheet metal, and has for its principal object the production of a bobbin of this class which is unaffected by atmospheric changes, is lighter, cheaper, stronger, and more perfectly balanced than those heretofore generally employed, and on which the thread will not stick or catch, as it often does on ordinary bobbins, between the head and shell. I attain these and other important advantages by my invention, in accordance with which I press one or both heads out of thin metal and unite them to the cylindrical metal shell in a novel manner; and in order that my invention may be clearly ascertained I shall first describe in detail the mode in which I carry my invention into practice, and then point out its several features in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in all the figures of which I have designated corresponding parts by like letters.

Figures 1, 2, 3, I, 5, and 6 represent Yarious steps in the formation of a winding-bobbin in accordance with my invention. Fig. 7 represents a modified formation of the shell of the bobbin.

In the manufacture of a bobbin, as shown, I press up in a die a circular or, it may be, only annular portion of a circular plate A of thin metal, as illustrated in Fig. 1. If said struck-up portion is circular, as shown, I generally prefer then to strike out the central portion thereof, so as to form an annular offset inneredge I3, and also to press up the outer edge, so as to form an upwardly-projecting flange O, as in Fig. 2. In this manner I may form either one or both heads for the bobbin.

I may form the cylindrical shell D for the bobbin of thin metal, either pressed out of thin metal, as shown in Figs. 1 to 6, together with one head E of the bobbin, having a flange F on its outer edge, or without said head E, or of one or more sections 0 of thin metal rolled or pressed into cylindrical form, as shown in Fig. '7, and having their adjoining edges united by an interlocking joint G, pressed flush on the outside.

The plain end of the shell D here shown is fitted closely and inserted within the offset edge or portion B of the head, as shown in Fig. 3, and the offsetv edge B, if the head is annular, as shown, is, by means of a suitable die, pressed inward so as to form a rim H, infolding the edge of the shell D, as shown in Fig. I. The folded rim II, together with the infolded edge of the shell D, is then bent laterally, preferably outward and downward upon the head, as shown in Fig. 5, so as to form a laterally-projecting flange I on the shell tightly clasped between the folds of the rim, and thus rigidly unite the head and shell and seal the joint therebetween against the possible entrance of any thread. I finally and by preference cover both heads of the bobbin with circular cover-plates J K, which I secure tightly to the heads by bending over the outer edges 0 F thereof, and I form the cover-plate J with an annular recess P to fit closely over the folded rim H, and thereby further strengthen and improve the bobbin.

I have shown gudgeons L secured to the heads of the bobbin by being fixed in the cover-plates J K, according to a prior patent, No. 501,897, obtained by me.

It is evident that the novel method of man ufacture and construction herein described is applicable as well to spinning-bobbins and to other analogous structures of thin or sheet metal.

By this invention I am, as before stated, enabled to produce a bobbin which has the important advantages of an accurate balance, extreme economy, lightness, strength, and clurability, and an absolute resistance to atmospheric changes, and which will not catch or injure the thread.

I claim as my invention 1. The bobbin formed, substantially as herein described, of a metallic cylindrical shell having a projecting flange at its end and a metallic annular head having its interior herein described, of a metallic annular head having a folded rim around its inner edge, a

metallic cylindrical shell having a laterally- I 5 projecting flange secured Within the fold of said inner rim and a cover-plate secured to vthe outer edge of said head.

In testimony whereof I have hereunto set my hand the 23d day of February, 1895.
